The products pf the NR-System are practically suitable for almost any application by reason of the galvanic separation of the power supply. The level controls are operated in floating mode - this means that the measurement current is not connected with any other potential current. The measurement process takes place exclusively in the substrate (liquid) and is therefore directly depended only on the physical properties of the substrate and the distance between the electrodes.
Sensitivity setting
The potentiometer is delivered in a centred setting as default. For most applications no "tune-in" is necessary.
Cable capacitance / length
The maximum cable capacitance and the resultant cable length are in direct relation to the required sensibility setting. Upon use of low capacitance cables for the measurement wiring (NR-device to probe) longer cable lengths are possible.

Level controllers

• The electrodes are feed from alternate current supply
• Wide range of the trigger level for functional reliability enven in the case
of varying media conductivity. Sensitivity calibration is rarely required
• Power supply and measuring voltage are isolated from each other
• Security cirquit: The ongoing process of filling and / or draining is stopped in
the case of supply voltage loss.

Level probes

• Individual assemblies available to meet Your preferences
• Electrode lengths are made to Your needs
• Electrode material in use as the standard product is V4A / 1.4571
• Up to 7 electrodes in one probe = 6 switching points
